Subject: [PATCH] ZKUI-238: Enable previous version for transition edition
 under certain conditions

If the `applyToVersion` in the existing workflow is `Previous version`
it should be selected in the form.

We disable the `Previous version` for the edition only both two
conditions are met:
1. the bucket is not versioned
2. the default value is `Current version`
